fitting interp Pi c th q xl n sri ns heseel v i Fig. 2 is an enlargedilongitudinal sectiontaken Centrally locetegl in thediscsfifi, 31 are registexf that of the rod 20 whereby the wall of the hole 32a will closely hug the rod and prevent leakage around the same. The hole 32a is disposed in coaxial alignment with the holes 30a, 3|a in the discs 30, 3|. In the discs 30, 3| at one side of the center of the discs are holes 30b, 3|b and in the compressible disc 32 between the holes 30b, 3; is an opening 321) here shown in the form of a slit. A flat narrow cleanout tape 35 may be inserted into the cylinder through the holes 301), 3| b and the slit 32b, The walls of the slit closely hug the cleanout tape and prevent leakage past the compressible disc 32.

The sealing device is also provided with openings through which a jointed cleanout rod may be introduced into the cylinder and into the sewer pipe. As shown the disc 30 is formed with an opening 39 and the disc 3| is formed with an opening 40. These openings, 39, 40 are disposed diametrically opposite the openings 3%, 3lb and the slit 32b, and are of a diameter slightly greater than that of the jointed cleanout rod. In the compressible disc 32 is formed an opening or hole 4! (see Fig. 3) of less diameter than that of the jointed rod, whereby when the latter is inserted through the opening or hole 4 I, the walls thereof will hug the cleanout rod and prevent leakage around it. The opening or hole 41 is disposed at an angle of approximately 90 to the openings or holes 39, 40 whereby when the slit 3% registers with the openings or holes 301), 3 lb a solid portion 42 of compressible discs is disposed between the openings 39, 40 thereby preventing any leakage through said openings. When a jointed cleanout rod is to be used, the ring 33 is unscrewed, the upper disc 30 removed and the compressible disc 32 is turned through an arc of 90, bringing the open ng or hole 4| to register with the opening 40 in the disc 3| and the other disc 30 is then placed upon the compressible disc with the opening or hole 39 in register with the holes 4| and 40 after which the ring 33 is screwed down upon the sealing device. In this position of the compressible disc, a solid portion thereof is interposed between the openings 30b, 3lb thereby preventing any leakage of water through said openings.

An ordinary faucet 36 may be secured in the wall of the cylinder to which a hose may be attached when it is desired to flush out the cylinder and sewer pipe and an opening 31 may be provided in the cylinder wall which is normally closed by a screw plug 38. The screw plug 38 may be removed and a pipe may be screwed into the opening 37 and used in flushing out the cylinder.

The faucet 36 may also be used to drain out any water standing in the cylinder above the inlet to the faucet.

In use the screw cap 39 is first unscrewed from the ferrule 15 and the rod 20 is fastened to the ears 2| of the screw plug l9 by the cotter pin 22. This connection may be made before the cylinder is screwed down upon the ferrule. After the cylinder has been screwed down upon the ferrule the rod 23 is rotated in a contra-clockwise direction thereby unscrewing the screw plug I v9 from the ferrule, after which the rod and screw plug may be raised to the dotted line position seen in Fig. 2. The tape or the jointed cleanout rod is thereupon inserted through the proper holes in the sealing device. If the water is standing at a higher lever than the cylinder, it may enter the cylinder through the ferrule 15, but it cannot escape therefrom. The cleanout tool is forced down through the-opening in the ferrule, through the opening in the branch H of the Y fitting and into the sewer pipe I0 wherein it may be worked back and forth in the customary manner to loosen the mass clogging the sewer pipe.

When the clogged matter has been loosened the cylinder and sewer pipe may be flushed out with clean water through the faucet 36 or through the opening 31 in the cylinder wall. After the sewer pipe has been cleaned out the tape or other cleanout tool is withdrawn and the rod 20 is lowered to bring the plug l9 into register with the opening in the ferrule and the rod is then turned in a clockwise direction thereby screwing the plug down tight, after which the cylinder is removed from the ferrule and the rod 20 detached from the plug. The screw cap 39 may now be screwed back in place on the ferrule.

While the invention has been shown and described in connection with a cleanout device for sewer pipes, obviously it has many other uses and may be used for cleaning out all kinds of pipes, whether containing water, gas or other liquids.

From the above it is apparent that I have provided a simple and eificent cleanout device and that one of several cleanout tools may be used without any danger of leakage from the cylinder.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

In a pipe clean-out device, the combination of a, ferrule adapted to be secured in a Y fi ting and 40 having internal and external threads at its upper end, a screw plug threadedly mounted on the internal threads of the ferrule, a rod for rotating said screw plug de achably connected to the plug, said rod forming the support for the screw plug when the latter is unscrewed from t e ferrule, a housing hav ng a threaded nipple at its lower end for connection with the external threads of the ferrule said housing being closed at its upper end with a r movable sealing device having two spaced metal discs each formed with a plurality of op positely disposed differently shaped openings therein, and a pliable washerdisposed between said discs, said was er being formed with openings therein corresponding to the openings in the discs and disposed at an angle of with respect to each other, whereby when one opening in the washer registers with registering openings in the discs a solid portion of the washer closes the other openings in the discs, said openings in the discs and washer selectively permitting a clean-out tool closely fitting the open ngs to extend through openings in the sealing device into the Y fitting.
